Specification of Letters Patent.

Application filed March 9, 19M. SeriaiHo. 823,455.

To all whom it may concern."

Be it known that 1, LEE S. YBURRIDGE, acitizen ofthe United States, and a resident of the borough of .Manhattan, city, county, and State of New York, have invented certain new and-useful Improvements in Add ing and Recording Machines, of which the following is a specification.

This invention relates to the same type of machine as disclosed in the application filed by ine ril 5, 1913, bearing the Serial Number 59,231, with such improvements and modifications as will appear.

, The frame of the machine has a top or supportin boardl00 inclined forward and downwar and provided with parallel slots 100 from front to rear (Fig. 1). These slots serve to receive the sliding key bars 101 which are provided with longitudinal grooves/"101, as seen in Fig. 2, and these grooves receive the key bar 101 and guide it in its sliding action. Each key bar carries a number plate 102 formed with'depres;

sions, as shown best in Fig. 2, so as to be engaged readily by the operators fingers. This plate is rigidly mounted .on the key bar and may bev made of eel- 'ed by means of studs 103 slot 103, Fig. 2.

stud 10 i luloid and Oto 9, the zero being at the lower or forward end. On the under sideof each key bar 101,-a rack bar 103 is mountseen in Figs. 2 and 2, whlch pass through the rack bar and secure the rack bar to the key bar. The plate 102 may have anupwa rd projection at its rear end 102 to facilitate the manual return of the key bar. formed. of right angled sheet metal, the horizontal portion being mounted on the key bar, as seen in Fig. 2*, and the downwardly depending portion has gear teeth out there- 1n, and at the upper or rear extremity a downwardly depending lug 10,3 of greater length than the gear teeth is provided with The slot 103 is-to receive the shouldered stud 104 provided on of a bell lever 104 fulcrumed on the, frame of the machine at 104*, and having a shorter rearwardly extending arm 104: provided close to its rear extremity with a shouldered extending through slot 105. provided at the lower end of the type bar 105, mounted to slide vertically in a comb 106, Figs. 1 and 2, provided with notches for the several type bars in their upper extremity. The stat onary pin 107 extends through the longitudinal slots 105 of all the type bars and assists in guiding the type bars, yet allows them to swing on said pin as a pivot in a transverse direction, so that the type bars may move slightly rearward (away from the bottoms of the notches in the comb 106 and to the left in Fig. 1) so-that the type 105 provided on the rear side and up per end 0 each type bar may be'moved toward a platen 108, journaled at 108*, on the.

against the platen by the compression spring 110 which can be released from pressure for straightening the paper by means of the upwardly projecting handle 112 2). It will be noted that the paper is fed between the platen 108 and feed roller 110 Patented Sept. 19, 1916.

The rack bar is (Fig.

the upper extremity and that instead of a narrow roll of paper, a wide sheet can be employedby passing it in the open space 113 left byreason of the C-shape of the frames supporting the platen and may project to any extent at either side of the machine, thereby enabling the insertion of paper of any desired width.

Each tyne-bar 105 carries ten number or digit types 105 arranged consecutively from 0 to 9 with the zeros at the upper ends of the type bars and they are normally held away from the platen by spring pressed rollers 114 (Fig. 2), mounted onthe ends of arms 114, j ournaled on the pin 107, one such arm being situated between each type bar and its adjacent one, there being as many rolls 114; as thefe are type bars. spring 11- 1 for each arm 111 secured at its upper end to a stationary shelf of the-frame of the machine tends to pull upthis end of the arm and apply pressure in a downward and rearward direction by means of the roller 114 upon the rear of the type bar 105, Fig. 2. When a key bar 101, by means of the plate 102, is moved down from the normal position shown in Figs. 1 and 2, the corresponding type ,bar 105 will be ra sed to bring that type 105 intoprinting line op- 6' posite to'the platen which agrees with the figure or number of the plate 102 appearing immediately above a frame plate 115, under which the key bars 101 disappear when moved down. The upper edge forming the pressure bar of this plate 115 is bent upwardly at 115 at an angle to form a convenient stop for the operators finger when moving the key bar downward. The pressure bar 115 may be separate from the plate 115 and adjustably connected therewith by slotted lugs 115 on said bar slidable on screws 115 in plate 115, to suit the fingers of differentjoperators, see Figs. 1 and 2. The disposition is such that when the key bar is moved down, the digit appearing immediately above the plate 115, the type bar will be raised so that the same corresponding type digit will have been brought'to the printing line. As long as no other part of the machine is operated, the key bars 101 may be moved freely and independently of each other downward from the normal posi-' tion and upward in case any error has been made in setting up an item which will appear in ,a reading line directly above the plate 115. At the right hand portion of the machine is located the main operating handle 116' (at the left of Fig. 1) mounted on rock shaft 117.

An arm 118 (Fig. 2) is rigidly secured to rock shaft 117 and pivotally carries at its free end a pawl 118 extending normally atsubstantially right angles thereto and presenting a contacting surface in the path of a hook or nose 11 that is pivoted at 119 to the frame. A

on a rocker arm 119 right angular extension 118 of pawl 118 bears against a stop 118 on arm 118 and is 'tensionally held by spring 118. Hence forcurved surface of a rocking plate 120 which is faston shaft 121 and has rigid therewith a hammer frame 122, said shaft also loosely carrying the hammers 123, normally supported by said frame in extended position for striking. a

Thereare as many hammers as type bars and they are impelled toward the type bars with increasing velocity in their approach on account of the rolling motion given rocking plate 120 by rocker arm 119. e The hammers 123 swing around the shaft 121 and are operated by means of the horizontal portion 122 of frame 122. .When the handle 116 is operated,,motion will be communicated through rock shaft 117, arm 118,

rocker arm 119 and rocking plate 120 to the hammer frame 122, said frame thereby carrying all the hammersv with it, until the pawl 118 slips off the hook or nose 119,

when the frame 122, rocking plate 120 and hammers will return to normal position by gravity, the rocking arm- 119 also resuming its normal position? under the influence of gravity and pressure of rocking plate 120. It will be understood that the rolling motion derived from the opposed curved surfaces of rocker arm 119 and rocking plate 120, and the angular relation between these members permits a relatively slow movement of handle 116 to be speeded up in transmission to hammer frame 122,.

through the rolling motion between rocking .arm 119 and rocking plate 120, to impart a degree of momentum to \the free hammers,

directed toward a projection 129 on a lever 129 forming part of a toggle with lever 130 to which it is pivotally secured at 130 and at its outer end at 130 to the arm 126 mounted at 126*. At the lower end of arm 126 is secured one end of a knife edge lock 131. There is a duplication of arm 126 and toggle arms 129, 130 to support the knife edge' lock 131 at each end and transmit parallel motion thereto, and these arms are rigidl mounted on their respective shafts, that. s to say toggle arms 129 are rigid with shaft 133 and arms 126 rigid with shaft V The spring 134: serves to return the toggle levers 1.29 and 130 and lock 131 to retain the latter in normal position. The type at h hook 119 to rocker arm 119 and rocker shoulder stud 138 on crank arm 138 bars 105 at their lower ends are provided with slots 105 with flaring openings with Which'the knife edge 131 of the lock engages. Normally, the lock 131 is clear of the type bars, but as soon as the main handle is operated and motion imparted to the arm 124, the pawl 125 will actuate the toggle levers 129, 130, and cause the lock to engage whateverfiaring slots 105 in the type bars 105 are opposite. The pawl 125 will operate the toggle levers-129 and 130 until they reach a straight line, and further contact, holding the toggle levers in this position, will depend upon the length of nose of pawl 125 and also its adjustment by the stop 125, the object of which is to maintain the lock in engagement with the type bars until after the hammers have caused the type bars to impinge against the platen. As soon as this. has occurred, the pawl-125 slips off the projection on lever 129 and permits the toggle levers 129 and 130 and lock 131 to resume their normal position by reason of the spring 134. It will benoted that pawl 125, after having slipped past the projection on lever 129. can in returning to normal position ride over it and resume'the position shown. Simultaneously the pawl 118 on arm 118 will ave communicated motion through nose or plate 120 and caused the hammers 123 to impinge against the. typebars 105 and caused the type thereon to strike the platen 108.

So far as explained, when the" handle 116 is operated all the type bars will be locked into alining position in whatever slots are opposite to the lock 1'31 and the hammers will be operated, causing all the type bars to impinge against the platen. To prevent the \impression of those type bars to the left of the item set up, in case such item requires less than the full complement of typebars, I provide a shutter 135 mounted on shoulder screw 136 (Figs. 2 and 10) located in the centpr approximately of the type bars and provided with a horizontal branch 135 pivotally connected to the link 137 at the bottom of which isathe slot 137* (Fig. 10) which is provided to receive a rigidly secured to the rock shaft 117. A spring 139 tends to bear the shutter toward theright (to the left in Fig. 1), namely for the turned lip 135. at the top to pass over all the type bars that have not been raised from their normal position. \Vhen the operating handle is at normal, stud 138 will contact with the upper end of the slot 137 in link 137 (Fig. 10 and return the shutter 135 j to the position shown in Fig. 1, but as soon as the handle 116 is operated, the stud 138 will move down and allow the link to be depressed by the spring 139 as the shutter the rotates around its pivot until arrested by the turned lip 135 coming in contact with a type bar raised above the normal or Zero position. The shutter extends to the left in Fig. 10 of the turned lip 135 and will serve to arrest any of the hammers 123 from coming in contact with the type bars 105 through being interposed between them. All those hammers to the right in Fig. 10 of the shutter will be free to come in contact with the type bars. Fig. 10 shows the'lip 135 in contact with the third type bar from the left and the shutter 135 is in front of the two left hand type bars in a position to prevent the hammers contacting with the latter.

It will be understood that in the oper ation so 'far explained, when the handle 116 is operated the type bars will be looked through their slots 105 being engaged by the lock 131 and simultaneously the hammer frame-122 and hammers 123 will be rocked around their pivot While at the same time the shutter 135 will be interposed between the hammers and type bars to the extent determined by the turned lip 135 contacting with the first type bar that is raised above normal or zero position and in acontinued movement of the handle the hammers will strike the type bars or the shutter 135 according to the location of the shutter determined by the item set up in the type bars. A continued movement of handle will release the hammers through pawl 118 slipping past the nose 119 which is timed to take place just as the hammers are coming in contact with the shutter while those hammers not arrested by the shutter will impinge against the respective type bars through momentum and immediately thereafter the handle will then release the lock. through the pawl 125 slipping past the projecting portion 129 of toggle lever 129. V

The gear teeth which depend from the rack bar 103 with which each key bar is equipped are adapted to engage with laterally projecting pins 140 arranged in a circle on the right hand sides (left in Fig. 1) of each of a series of number or registering Wheels 140 which I term adding wheels. These adding wheels are loosely mounted on a vertically shiftable shaft 141, which is mounted in supports 142 at opposite sides of the machine (Figs. 3 and 4), said supports being provided at their lower ends with longitudinal slots 142 engaging shoulders of screws 142 secured at each side of the frame and permitting movement in a perpendicu lar. direction, while at the upper ends the supports 142 are mounted on studs 143 rigidly fastened to arms 146 journaled to the frame at 146" at each side of frame and connected together by the strap 146 seen in cross section in Figs. 2 and 3. To the stud transverse rock shaft 145.

143 is mounted the lever 144 pivoted at 145 to lever 145 which is rigidly secured to and 145 form a toggle joint for raising and lowering the adding wheels into and out of engagement with the rack bars 103. There is a duplication of the toggle joint at both sides of the machine, the levers 144 and 145 being at the right side while at the left the levers 213 and 212 (Fig.- 9) have the same diniensions and will be referred to later.

The toggle joints aforesaid are operated by a reciprocating bar 147, (Figs. 2 and 3) pivotally connected at its rear end with an arm 14! extending upwa'rdlj from rock shaft 117 and having like connection at its forward 'end' with a swinging arm 147". pivoted at 147 to the frame. Bar147 bears the oppositely directed pawls 148, 149,

pivoted at their adjacent ends, as at 148 and 149*, respectively, and tensionally held normally in substantial parallelism with bar'147 as by spring 147 which draws them respectively against stops 148 and 149 on bar 147. The end faces of pawls 148, 149 are extended downwardly for operating purposes, pawl 148 in the forward movement of bar 147 meeting in its path a pin 145 on toggle lever stop to limit the movement of the toggle joint at each end. At this point in the movement of bar 147 pawl 148 will slip over pin 145 and during its further progress pawl 149 will slip over pin 145 on lever 145 which has entered the path of'said pawl. .In the return movement of bar 147 (with the backward swing of handle 116 under the tension of spring 116 Fig 8), pawl 149 williineet pin 145 and operate the. toggle joint to lower shaft 141, removing adding wheels 140 from engagement with rack bars 103. This return toggle action so far as slack therein is concerned, is assisted by a spring 150 pulling upon a lever 150 fulcrumed at 150 and connecting by a pivotal link 150 with le'ver 144,

said link exerting a thrust upon said lever whenever the-link is beyond the vertical position and thereby exerting tension in either direction as also a locking action by pressure of either end of slot 145 against pin 144.

During the time thatthe teeth of rack bars 103 are in coiiperative engagement with the adding Wheels 140 (which is during that part of the forward movement of bar147 in which pawl 148 has acted upon pin 145 to straighten 'toggle levers 145 and 144, thereby moving the adding wheels toward rack bars 103) the adding wheels 140 are rotated owing to the rack bars 103 being re- The levers 144' v be understood,

mesa-3211' turned (slid rearward or upward) to their original positions by the following mechanism: Pivotedto rock shaft 117 and extend ing forwardly therefrom is a lever 151 to which is pivoted at 151 another lever 152 forming a toggle joint (Figs. 2 and 3), the free end of lever 152 being pivoted at 152 to a rocker arm 153 fulcrumed on shaft 104 and having forward extensions 153 carrying a transverse. bail or universal bar 153 which lies normally in advance of. the bell levers 104, which I term'sub-levers, said bail being adapted to return the sub-levers, with the rack bars 103, key bars 101 and typebars 105 to their original positions, after they have been set through'the manual operation ofthe finger keys. There is a duplication of levers 151, 152 and 153 in order to insure parallelism of movement. The complete fprward pull of handle 116 accomplishes the aforesaid result, this action straightening out toggle levers 151 and 152 and causing rocker arm 153 to swing about shaft 104' with diminishing speed, bail 153 in the are of its travel thus proyided meeting the sublevers 104 in their set positions and returning them with their associated members without undue jar or shock because of the diminishing rate of travel consequent to the toggle action. The adding wheels 140 will therefore be rotated by the racks 103 belonging to the key bars 101 which had previously 7 been moved from their original positions.

According to the greater or smaller extent to which the key bars 101 and rack bars 103 had beenmoved, their return movement will be greater or smaller and the adding wheels 140 will be rotated correspondingly. It will of course, that' the number of spaces or divisions of the plates 102 will agree in width with the teeth of rack 103,"

and that each; of the wheels 140 has ten teeth or pins 140 and bears on'its periphery ten consecutive number indications (0 to 9). While the key bars 102 are set at such distances apart as' will allow them to be operated conveniently by the users fingers, the

type bars 105 are set together much more closely, corresponding (more or less) to the letter spacing customary in-recording machines.

The wheels 140 which are mounted to turn freely upon their shaft 141 are engaged against rotation when in their normal or. lower position, after disengagement from the keybar racks, by pins on each wheel meshing between the upstanding teeth 154 (Figs. 2 and 4) of vertical carry arms 154, pivoted, one carry arm for each wheel, on a fixed shaft 155. Also mounted on shaft 155 is a frame consisting of upwardly extending arms 155. in pivotal engagement by links 155", with extensions 155 of rocker arm's 153 at each side; the forward arm's 1 5 of said frame carrying a transverse bail or universal bar 156. Tension is applied to carry .arm's 154 by springs 154 to draw them forwardly in carrying against a stop, as 154,- and said carry arms are adapted to be set to-the trippingposition' by being rocked rearwardly and momentarily re- 1 shown on the side of the wheel'opposite to that carrying the pins 140 (Figs. 2 and 4).

This tens pin extends tangentially from the Wheel perimeter over a portion of the wheel radius and thence centrally to its hub, in this manner serving a twofold purpose to be referred to hereinafter. The carry arms 154 each have a pawl 157 pivoted thereto at 157 and extended out to be in the path of a right angular tooth 158 at oneend of a horizontally swinging bar or trip lever 158, pivoted at 158 to a trans verse, bar 159 secured to each side of the machine frame, duplicate bars, 158 being provided for each of the adding wheels, exceptfor that one at the extreme left side of the machine, or right side of Fig. 1, which has a modified swinging bar 158 having hook 158 tensionally held in the path of the tens pin of its adding wheel to serve as a solid lock therefor. The opposite end of each swinging bar 158 has a right angular tooth 158 (Figs. '1 and 7) in the path of one of a series'of lugs 160 which project rearwardly from a transverse bar 160, pivoted by links 160 to'the frame, one of saidlinks'160 having a right angular extension 160 having a projecting stud 160. Said stud 160 is in the rearward path of the offset nose 161 of a pawl 161 that is pivoted at 161*"to the forward extension 146 of right hand arm 146, which arm may be. termed a rocker arm because it rocks on its fulcrum 146 in the vertical shifting movement of supports 142.

j The pawl 161 is drawn over an eccentrically mounted stop 16]. by a spring 161 to be incapable of forward motion, and said cam may be adjusted to vary the angularity of said pawl in its set position. With a downward rock motion of" extension 146", caused by the upward shift motion of supports 142, the offset nose 161 presses against stud 160 and through said stud and bell lever 160", 160, swings bar 160 to the right in Fig. 1 causing the teeth 160 on said bar to rock the swinging bars 158, (or such of them as have been displaced) back to their positions'in line with the pawls 157, inreadiness for holding the carry arms 154. Said ofiset nose 161 by reason of its upper cam surface passes under stud 160 near the limit of its movement, thereby releasing said stud tens pin 156, to be shifted longitudinally by said tens pin in the rotation of its addmg wheel, and thereby to release said bar 163, at its other end, from engagement which it had by a stepped recess 163 with a lug 164 on a rigid transverse bar 164. As thus released the bar 163, with its associated bar .158, is swung on pivot 158 under the tension of spring 165 which extends rearwardly in a diagonal direction from the forward end ofbar 163 to bar 159, as shown by dotted lines Fig. 6, the rear ends of bars 163 and 158 under the same influence, being moved away from their associated adding wheel, that is to say, projection 163 will be out of the path of its tens pin 156 and the tooth 158 of bar 158 is removed from,

the path of pawl 157 -on carry arm 154 to the left thereof (to the right in Fig. 1), freeing said carry arm and allowing the tension of its spring 154 to draw it forward to the carrying position, namely against stop 154. The bars 163, 158 will be retained in such tripped position by reason of the tension of spring 165 drawing them to the right (left in Fig. 1) and drawing bar 163 to the rear (left in Fig. 6) until the trans- Verse bar 160 is operated, as heretofore explained, and by means of the lugs 160'- caused to reset those bars 163, 158 which have been tripped, by hearing them to the left (right in Fig. 1) until lug 164 is opposite to recess 163 and by reason of the tension of spring 165 to engage said recess and thereby retain the bars in their normal position. The tripping action of bars 163, 158 by the tens pins 156 may take place in either position of the adding wheels since the tens pins are longer than the shifting movement of the adding wheels by the toggles 144, 145.

tion and return them to normal position and the key bars 101.to zero, at the same time turning wheels 140 the number of teeth-designated by the item set up. During such rotation of the adding wheels if any wheel is moved beyond nine then between the movebeen held practically ment of that wheel between 9 and 0 the tens in 156 will actuate the corresponding tooth 163 of bar 163 and cause it and bar 158 to be tripped'by the action of spring 165, simultaneously the rear tooth 158 will release its corresponding carry arm 154' through moving out of the path of the pawl 157 and the spring 154 will then impel the carry arm to the stop 154 as shown in dotted lines in Fig. 2. Such movement of the carry arm 154 will not be effective because the adding wheels zbeing disengaged therefrom and meshing with racks 103 no result will ensue until later. 1

(The bail 156 which receives a'rearward impulse through the links 155 meets the forward edges of those carry arms 154 which have been tripped into the carrying position, and moves said advanced carry arms rearwardly against the tension of their springs 154 to a rearward position where their pawls 157 will lie behind the tripping levers 158, said bail tarrying under its toggle actuated action aforesaid in said rearward position. The operating handle will now be at the end of its movement and when released -it returns by tension of spring 116 and the pawl 149 on bar 147 comes in contact with pin 145 causing a breaking action of toggle levers 144, 145 and the unmeshing of the adding wheels with racks103 and engagement of the adding wheels with the carry arms 154 which in the meantime have inert by the bail156'. Upon the further return of the operating handle 116 the bail 156 will move away from the carry arms 154 and any carry arms that 'tooth 156' will cause a are not retained by rear teeth 158 of bars 158 by contact with the respective pawls 157 will by reason of the tripping action of bars 163, 158, be caused to carry their corresponding adding wheels one tooth as will now readily be understood. If any wheel so carried happens to move from 9 to 0 its tens tripping action of bars 163, 158 thereby releasing the carry arm in engagement with the adding wheel of the next higher order to the left (to the right in Fig. 1) to be carried one tooth by the same process.

be reset and the carry arms will likewise remain in their abnormal position (those that have been released) until the operating handle is operated and bail 156 returns them to normalposition.

The reading line of numerals upon the wheels 140 is visible to the operator through observation openings 115 in the frameplate 115 of the machine. I t eachreturn stroke of the handle 116, the platen 108 is turned so as'to obtain the proper line spacing. For this purpose a curved link 170 is connected by a slot 170 to the tail of arm 118, by pin 170* (Fig. 2) and extends upwardly against one of the C-shaped side frames, 109 to one arm of a bell-lever 171 pivoted at 171 to said frame, a second curved link 170 extending from the other arm of said bell-lever to a rocker arm 173 mounted on the platen shaft 108?, said rocker arm carrying a pivotal dog 17 3 adapted to engage with a ratchet wheel 174 that is fast on shaft 108 to rotate. said shaft and the platen the space of one or more ratchet teeth with every return stroke of handle 116, a spring 171 causing said dog 17 3 to ride over one or more teeth upon the forward stroke of the handle. A detent 17 4 is pivoted at 17 4 and'held by a spring 174 against the teeth of ratchet wheel 17 4 to retain it in position.

A particular advantage accruing to theriod callyz A frame 180 (Fig. 1) extending transversely 'ofthe mach1ne,-in advance of the platen, is centrally pivoted to the machine frame, as by pivot 180", on which it is adapted to rock horizontally. Said frame rotatably carries a parallel shaft 181, having the oppositely cut worm threads 181", 181 near its respective ends, which threads are adapted to alternately enter into meshed engagement with respectlvely adj acent gears 182, 183 which themselves are respectively associated with ribbon spools 182, 183, having ink ribbon carried thereby and extending between said s ools across the line of work. A ratchet wlieel 184 mounted at one end of shaft 181 is adapted to be turned (ste by step) or a number of teeth at one stro e, by a pawl 184 pivoted to an arm 185, secured by a shoulder rivet 185" to a vertical link 185 that is pivoted at its lower end to the extremity of an arm 186 extending forwardly from rock shaft 117 (Fig.

mes-eat means described, will cause the ratchet wheel 184, carrying shaft 181 to be rotated one step or a number of ratchet teeth. The

means by which this feed movement is alterdisk 188 on shaft 181. The extended portions of arms 187 are connected with a spring 188*, serving to hold said arms normally drawn inwardly against stops 188", and holding the arms'185 outwardly extended. The feed movement is communicated by one of the worm threads to the gear on its adjacent spool until the other spool has been emptied, at which-time the inwardly directed tension of the taut ribbon against upright stud 185 of arms 185 belonging to the emptied spool, as the spool 183 in Fig. 1, draws the associated arm 187 outwardly, whereupon the conical, or projectile nose shaped projection 187 on arm 187, having the peripheral edge of the disk 188 connected with worm thread 181 in its path, slides over said cam disk, and on account of the conformation aforesaid of said projection 187 rocks the shaft 181 to disengage worm thread 181 from gear 182 and simultaneously engages worm thread 181 with gear 183, thereby reversing the direction of travel of the ribbon. This move- 'ment- 1s reversed when spool 182 becomes emptied. A detail of the lock for retaining the meshed engagement between a worm thread and its gear until disengaged by the positive means just described is shown in Fig. 1, wherein the frame 180 is seen to carry a pin 189 having a link189 pivoted at 189 to lever 189 fulcrumed at 189, a spring 189 exerting tension on said lever, link, and frame to hold said frame tensionally locked in either. position to which it may be rocked. A pivotal detent 190 is spring held against each gear 182, 183 to prevent free or accidental rotation of the ribbon spools. turned by hand when desired, by means of a milled knob 1083.

In order to compel the user to give the handlellfi a complete forward throw, until it engages a stop 200, I provide the following mechanism which prevents the return movement of the handle until it has been brought fully forward: Referring -to Fig. 8, on the rock shaft 117 is secured a toothed The platen 108 may be sector 7 201 adapted to engage a pawl 202 fulcrumed to a shaft 202 which also carries a movable member to be described hereinafter, and pulled (when free) by a spring 203' in such a direction as to standnormally radially with respect to the sector. That is to say, the center of the shaft 117, the fulcrum 202, and the fixed end of the spring 203 are in a straight line. Normally the sector 201 is not in engagement with the pawl 202. When the shaft -11 is swung forward from its rear stop 201 the sector 201 comes in engagement with the pawl 202 and swings it on its fulcrum (contra clockwise in Fig. 8) so that the pawl no longer stands radially, but will prevent a return of the sector 201 and shaft 117. The pawl will of course allow the forwardmotion of the sector to continue. At the end of this forward motion, the pawl 202 will slip off the rear edge of the sector 201, and the spring 203 will at once restore the pawl to its radial position. The return movementof the shaft 117 is no longer prevented.

,During such return movement, the sector 201 will again come in engagement with the pawl 202, swinging the latter on its pivot in the opposite direction (clockwise in Fig. 8), so that the'return movement of the shaft 117 must be completed before said shaft can be moved forward again.

From the above description it will be clear how the items are set up and printed on paper, also how the total is registered by means of the adding wheels 140. have to describe the mechanismfor printing the totals and for setting the adding wheels 140 back to zero. At the left hand side of the machine (to the right of- Fig. 1) is located the zero handle 204 carried by a rock shaft 205 provided with a sector 206 (Fig. 9) having stops 206, 206- respectively to limit its rearward and forward movements which in the arc of its travel forwardly meets'and is held against return by a pawl 207, fulcrumed at 208 and held by spring 209 with respect to sector 206 in the same 1 still manner as the pawl 202 is held with relation yond the influence of said pawl, and said pawl 207 operating similarly as a bar against retraction of said sector 206 in the return path of the latter. One function of the zero handle 204 being to'cause the return of the adding wheels totheir zero positions (namely to their rotated positions where the zero characters on said wheels areexposed through the observation openings 115?), I provide an arm 208 extending u wardly from rock shaft 205 (Fig. 8-), said arm having a pin and slot connection with a link 209, pivoted at 210 to a spur 210 on a toothed segment or quadrant 210, fulcrumed at 210 to one of thesupports 142 for wheel members as exists between stud 142 and slot 142 in the range of reciprocating movement of support 142. The teeth of segment 210 and pinion 211 are continually in mesh,'and any slack or lost motion in said segment, after its return to normal position, is taken up by aspring 211 attached to spur 210 and exerting upward tension thereon. It will thereforebe seen that the forward movement of zero handle 204 through the instrumentalities described, the segment 210 having as many teeth as pinion 211, accomplishes a complete reverse revolution of shaft 141. In order to note the efiect had by this movement of shaft 141 on the adding wheels, it must be remembered that the wheels 140 are normally free to rotate on shaft 141, excepting in their'lower position where they are enmeshed with the carry arms 154, by

which they are held against rotation. The Ewheel return" or zero setting mechanism is however operable when the wheels 140 have been raised by the toggle mechanism previously described as controlled by the forward movement of handle 116, which toggle mechanism is also controlled by the zero handle 204 in the following manner.

Mounted on rock shaft 145 (Fig. 9) is a lever 212, pivoted at 212 to alever 213 and forming therewith a toggle joint disposed at that side of the machine opposite to the toggle levers 144, 145, said lever 213 also being pivoted on a stud in line with stud 143, whereby the toggle joints-at both sides of the machine may operate in unison.

In order to operate the toggle joint included in the zero handle train of mechanism, I provide an arcuate lever 214, fulcrumed to the frame at 214 at the rear of shaft 145 and at the upper forward endof said lever it is connected by a pivoted link 214 by pivotal engagement at 212 with lever 212, near the upper end thereof, in such arrangement that a forward thrust of link 2114 (to the right in rig. 9) impelled by lever 214, upon lever 212, will straighten the toggle joint of levers 212, 213, thereby accomplishing the same elevating act for shaft 141 as that described in the operation of the toggle levers 144, 145. The impulse referred to as imparted by arcuate lever 214 is derived from the sector 206, through a pawl 215 pivoted on the side thereof at 215, and held with its forward end substantially in the direction of travel of said sector by a spring 215 drawing the rear end of said pawl against a step 215". As thus supported, the path of said pawl 215 in cludes astop pin 214 on lever 214 ar'" the forward movemeft of sector 206, through pawl 215 and pin 214 is therefore communicated-to lever 214, link 214 and toggle lever 212, for the purpose set forth. When the sector 206 has moved so far forward that the toggle joint acted upon has become straightened out or extended in full, the directional positions of pawl 215 and pin 214 will have altered to the extent that awl 215 will slip under pin 214 and there ore cease to exert pressure thereon.

In the further advance of sector 206, (the 'rock shaft 205 Fig. 8 requiring to continue its motion in order to actuate the gear sector 210, the lost motion in the pin and slot connections therewith having been absorbed during that part of. the rock shaft motion eifective in straightening the toggle joint), a rearwardly directed awl 216, pivoted at 216 to said sector, an normally drawn at its rear end against a stop pin 216 by a spring 216, slips over the stop pin 214, and thus has said stop, in in its path on the return movement 0 sector 206. Thus the setting of the totals on the type bars into printing position is accomplished by the forward movement of zero handle 204, which movement first raises the adding wheels, with their accumulated enumerations, into mesh with racks 103, and then through gear sector 210 and pinion 211, (with the aid of means to be described) turns said wheels back to zero, in that act said wheels carrying with them the racks 103, and, consequently, causing the sub-levers 104 to move the type bars 105 to bring types bearing the numerals representingthe total into printing position. v

The assisting means in the zero setting operation stated as requiring description comprises a sliding feather or spline 217 located in a groove 217 in shaft 141, said spline carrying teeth 21'.. which are normally out of the rotary path of the tens pins 156 on the adding wheels, said teeth 21'? being held in their normal disengaging positionsby means of a spring 217, placed in a hollowed out end portion of said shaft, and exerting pressure against a plunger 217 which lies between said spring and spline 217 and presses the latter from right to left, in Fig. 4, the opposite end of said spline hearing against a plunger 217 which under the normal condition recited extends at the left (Fig. 4) beyond the shaft. The end of said plunger 217* is adapted to he met by a rocking dog 218, pivoted at 218*, by the cam surface 219 of a segment 219 (Fig. 9), pivoted at 219 riding up under a right angularly extending 218 of dog 218, rocking said dog inwardly and causing it to retract plunger 217 with spline 217 against spring 217, in this act bringing the teeth 21? of said spline into the path of the inner radial portion of the tens pins 156*, whereby the rotatieh of the 141 aforesaid its spline teeth meet the tens of projection 163", the trip bar 163 is merely forced at its other end against lug 164 ter back to zero. without effect, while in the adding and The cam segment 219 referred to as the carrying operation the tens pin contacts on operating member for dog 218, is fulcrumed vits left side with projection 163 in Fig. 6. at 219 has an extending arm 221 pivoted By reason of the tangential arrangement at.221 to a link 221 which is pivoted at 221 of each tens pm 156 from a given point in on sector 206, which sector, as a rigid part the radius of its wheels 140 out to the peof rock shaft 205, is the prime mover in the riphery thereof, the extent of this tangenpins of the adding wheels and turn the latshifting action of the shaft 141 just referred tial arrangement covering the range of vertical movement of the wheels, the wheels are retained at the zero position more acto. Also in the forward throw of handle 204, a link 222, extending upwardly'from a pivotal connection at 222 with a rearwardly extending arm 222 from rock shaft pins were radially disposed at the time when 205, and having pivotal connection at 222 the wheels return into engagement with the with a sector 223, fulcrumed at 202, swings carry arms 154. The disposition is such that said sector 223 rearwardly in the performance of the following functions: Said sector wheels and the position of the tens pins at 223, upon wh oh the pawl 202 is spring held thlstime are parallel. The adding wheel 130 by spring 203 in its normal position holds Ilght in Fig. l is arrested at the zero posaid pawl operatively with respect to its Il y he pawl 158 which permits the engagement with sector 201, but when swung t ns pin t0 ride past while rotating in the rearwardly by link 222, thereby moves pawl other dlrection in the act of adding.

It will be observed in Fig. 6 brate said rock arms vertlcally and thus to that when a tens pin abuts on the right side move the ribbon which is carried 1n vertical curately than wouldbe the case if the tens the direction of shifting movement of the slots229 in the rearward ends of said rock arms from the lower to the upper position. After the total has been printed as described, and the zero handle allowed to return to its original position, two different operations are .now possible. If the adding operation has been completed, that is to say, if the printed total is the final result, the key bars 101 which have been lowered by the zero-setting mechanism, are pushed back by hand to their original upper or rear position. This restores all the parts of the machine to the initial or zero position. In some cases, however, the total printed is'not the final total, but an intermediate result or subtotal, that is to say, it is desired to continue adding items to such subtotal. In this case, afterthe zero handle has returned to its normal position, those key bars 101 which are in the lower or forward position are not returned by hand, but the handle 116 is given a complete forward movement in order to set up in the wheels the same item as was removed from them in the zero setting operation, in other words, the adding wheels 140 are rotated by means of the rack bars 103, during the return of the key bars 101, so that when the handle 116 comes back to its initial position, the key bars 101 and the type bars 105 will be in their normal positions, but the adding wheels 140, instead of standing at zero, will show the subtotal which has just been printed in purple, being a duplication of the total that was printed in red.

It is very important to prevent the zero and total setting mechanism from being operated while one or more of the key bars 101 and the type bars 105 are out of the zero position. In fact, the zero and total setting device should be operated only with all the key bars 101 in their normal or rear position. For this purpose, each .of the levers 10 1 is protjded, adjacent to its fulcrum, with a forwardly facing cam or heel 230 (Fig. 2), and whenever a key bar 101- is moved down (forward), the corresponding cam 230 will push downward on a rod 231 extending across the levers 104 and carried by two arms 231 fulcrumed on the frame at 231', said arms being tensionally drawn toward the frame by spring 231' to normally hold rod 231 in a depressed'seat'231 therefor in cams 230 (see Fig. 2). Hanging from a pivot 232 (Fig. 5) borne by an extension 232 of a frame portion which carries the shaft 104 is a pawl 232", to which is connected a. spring 232 tending'to draw said pawl to a position in the upward path of an arm 233 on the fzero'shaft 205, where said pawl will serve as a stop to prevent vertical movement of saidarm and thus to lock the .zero shaft against operation. But the rod 231 is normally held to prevent forward.

movement of pawl 232 by spring fiiil said rod lying in a slot 232 in a link 232 which is pivoted at 232 to the rear extension of pawl 232".

The rod 231 is forced againstthe upper end of slot 232 by spring 231 which is stronger than spring 232 and thereby normally retains pawl 232 out of the path of arm 233, but when a cam 230 is operated, the rod 231 will be moved down and the spring 232 will then become effective to bring pawl 232 into the path of arm 233,

thus acting as a stop for the zero shaft as stated. This construction will also permit of the return of zero handle and arm 233 when the key bars have been left with the total set up because the pawl 232 will then be pushed out of the way by the arm 233.

Referring to Fig. 3, it will be observed that also the arms 153 which carry the universal bar or bail 153 have beneath them cams=234 adapted to ride over and depress rod 231 to lock the zero shaft when said bail is moving in the performance of its function in returning the sub-levers, said cams 234: having forward inclines 23st which allow them to freely leavetheir normal posiiition behind said bar and to depress the latter, the main function of said cams 234; being to lock the zero handle when the operating handle starts to move.

To assist in imparting a comprehensive knowledge of the operation of the various parts in my invention, I will briefly describe hereunder, as far as possible in sequence, the several manual and major mechanical performances therein: The machine being at normal the operator sets an item by sliding the finger key bars downwardly until his finger, bearing against a numeral, comes to rest against stop 115. In thus setting the keys the sub-levers 101 will have moved the type-bars 105 to bring the corresponding type in printing relation with respect to the platen. The operator then pulls the handle 116 through a full stroke. The first part of that stroke operates the hammers 123 through bail 122 and rockers 120, 119 by the action of arm 118 that extends from handle shaft 117. At the same time the shutter 135 has been interposed by selective means be tween the typebars and those hammers which are not to impact with type bars. While operating the hammers the lock 131 is applied to the type bar racks 105 through toggles 129, 130 through the action of pawl 125. The reciprocating bar 147, also 0perated by the handle through arm 117, has

..gagement with spring pressed carry arms 154, andtaking said wheels into mesh with the racks 103 carried by the sliding key bars 101. The upper toggle member 144 has connection with rock arm 146, whose forward extension 146 has a pawl-161 which, in the toggle straightening action aforesaid shifts a toothed bar 160 and causes the teeth of said bar to set such of the trip-bars 158 as had been tripped back into their normal position where they act as stops to hold the carry arms 154 in normal position. After straightening the toggle joint aforesaid, the bar 147 continues its forward movement to the limit of the handle stroke to cause pawl 149 to come in front of pin 145 on toggle member 145 in readiness for the return movement. Also in that forward movement of handle 116 the toggle joint 151, 152 has expanded, and, when the wheels have entered mesh with racks 103, the bail 153,

actuated by said toggle joint, with diminishing speed has moved toward the sub-levers 104 in their variously set positions and carried them back to normal position, thereby returning the key bars to zero. With the movement of toggle 151,152, another toggle composed of members 155 155 at the same time moves the bail 156 with diminishing speed toward the carry arms, to reset those that have carried. It will be seen that in the first part of this handle movement the hammers, Which were swung for printing, Were also released for return by the pawl 118 passing over nose 119 to release the rocker 119 and it will also be seen that the return of the finger keys to 'zero causes the return of the type bars to zero through connection 104. It should be noted that the spring 150 exerts tension to pull down lever 150 'when link 150 is out of line at either side with'toggle member 145, thereby assisting the toggle action in both directions in vibrating or shifting the wheels.

The spring actuated return stroke of handle 116 causes pawl 149 to break the toggle joint 144, 145, returning the wheels, with the item set thereon, to their seats in the carry arms. The wheels in their rotation in the forward stroke, will through their tens pins 156 have tripped any trip levers 158 in the path of said tens pins and thus the carry arms 154, which rengage said adding wheels in the first part of the return stroke aforesaid, before bail 156 leaves them, or due to the slow movement of said bail When in that position; having reengaged said wheels, are enabled, if their trip bar stops hay e been tripped, to move to the carry position and cause their engaged wheels to carry. The continued return movement of handle 116 has no further function so far as the'major elements are concerned, eX- cept to restore bails 156 and 153 to normal position, also to return the shutter to normal. The turning of the platen for feeding the paper and feeding the ribbon longitudinally are also performed.

The zero handle 204, in its complete stroke performs no adding operation, but through toggle joint 212, 213 moves the adding wheels from the carry arms 154 to theracks 103, and through segment 210 and gear 211 on shaft 141 turns the wheels backwardly, communicating the total number or sum alined on the wheels to the finger keys at the setting line, and also to the type bars at the printing line. In this act the wheels 140 may have been removed from the carry arms 154 Whether they were in normal or carried position, or some in each, and, on the return stroke of the zero handle said Wheels will be returned to the carry arms in the same positions of the latter. It will also be noted that the zero handle in its movement through toggle joints 212, 213 thereby shifting the adding wheels also re? sets the trip bars 158, 163 or those that have previously been tripped through the pawl 161 on arm 146 imparting movement to transverse bar 160.

It is believed that the means by which the Zero handle forward stroke causes the engagement of shaft 141 with the wheels and returns them to zero is quite apparent, as also the interlocking means preventing the handles 116 and 204 from operating to gether, and the exception that the handle 116 may move for the printing operation alone when the handle 204 is fully thrown; also that all other actions and interactions are fully described.
